    • 摘要: 一种杀菌组合物及其用途本发明提供了一种杀菌组合物及其用途。所述杀菌组合物的主要活性成分包括两种组份,组份一:双胍三辛烷基苯磺酸盐;组份二:丙硫菌唑,其中,组份一和组份二的质量比为1:20〜20:1,两种组份总质量占组合物总质量的百分比为5%〜80%。该组合物减量增效,毒性低,对人畜及生态环境危害小,同时可以延缓病原物抗药性的产生和发展,对黑星病、白粉病、黑斑病、褐斑病真菌性病害有较好的防治效果,具有广阔的应用前景。
    • 摘要: 烷基苯磺酸盐,堪称日常生活中随处可见的“绿色精灵”。它不仅是制备餐具洗涤剂的原料,还能施展“魔法”,迅速去除物体表面的污渍。烷基苯又名十二烷基苯,无色透明液体,有芳香味,主要用作表面活性剂原料。需要注意的是,它可以发生磺化、酰化和热裂解反应,应储存于阴凉、通风的地方,远离火种、热源,避免与氧化剂接触。

    • 摘要: 研究了脂肪醇醚硫酸钠AES/烷基苯磺酸盐SAS复配体系在高矿化度条件下与原油间的界面张力.结果表明:复配体系在高矿化度地层水中具有良好的溶解性,能在较宽的加量范围内(0.05%~0.70%)与原油形成超低界面张力;在优选的复配体系(总加量0.3%,m(AES):m(SAS) =1∶1.2)溶液中加入单一无机盐NaCl,界面张力先下降后升高,在60 000 mg/L NaC1溶液中界面张力可降低至10-4 mN/m;复配体系在Ca2浓度为200 ~ 800 mg/L时,界面张力可维持10-3 mN/m,适量增加AES比例能进一步改善复配体系抗盐能力;复配体系与石英砂混合吸附72 h后仍保持超低界面张力.表明该复配体系性能优良,满足高盐油藏开发需求.

    • 摘要: Combined with synchronized monitoring techniques, the active constituent in the sample of alkylbenzene sulfonates was separated and purified by liquid-liquid extraction method.The results showed that the active constituent with higher purity can be obtained and the content data were more accurate adopting the present optimized purification process.Meanwhile, the residual content of active constituent of alkylbenzene sulfonates in the coexist constituents, such as unsulfonated oil, inorganic salts etc.was less than 1% of the total active amount.The content of active constituent of alkylbenzene sulfonates increased from about 39% to 48% compared to the purification process that is usually used previously.%结合同步监控技术,采用液-液萃取法对烷基苯磺酸盐样品中的烷基苯磺酸盐活性物进行分离纯化.结果表明,优化后的纯化工艺可以获得纯度较高、结果更为准确的烷基苯磺酸盐活性物组分,样品中其它共存组分如未磺化油、无机盐等中残留的烷基苯磺酸盐活性物的量小于总活性物量的1%;采用优化后的纯化工艺获得的烷基苯磺酸盐活性物质量分数较常规纯化工艺有明显增加,从39%左右增加至48%以上.

    • 摘要: 结合同步监控技术,优化纯化工艺,获得总烷基苯磺酸盐活性物组分以及单烷基苯和双烷基苯磺酸盐活性物组分,纯度大于90%;分别以总磺酸盐活性物和单磺酸盐 、双磺酸盐活性物为定量标准物质,对烷基苯磺酸盐样品中的活性物百分比进行高效液相色谱分析.结果表明,烷基苯磺酸盐样品中单磺酸盐的量远高于双磺酸盐;总磺酸盐 、单磺酸盐和双磺酸盐活性物组分均在224 nm处有最大吸收,吸收系数强弱顺序为单磺酸盐 ≈ 总磺酸盐>双磺酸盐;以总磺酸盐和单磺酸盐活性物组分为标准物质,最小检测量为5 mg/L,以双磺酸盐活性物组分为标准物质,最小检测量为10 mg/L;由于双磺酸盐活性物组分紫外吸收系数较弱,导致以总磺酸盐活性物为标准物质测试的百分比结果较同时以单磺酸盐 、双磺酸盐活性物为标准物质时低3%左右.%Combined with synchronized monitoring techniques ,purification processes for active constituent of alkylbenzene sulfonate have been optimized ,and the total alkylbenzene sulfonate ,mono-alkylbenzene sulfonate and di-alkylbenzene sulfonate can be obtained with purity over 90% .With the above active constituents as standard substances respectively ,the determination of alkylbenzene sulfonate content in the original samples was carried out by high performance liquid chromatograph .The results showed the sample contained mono- and di-alkylbenzene sulfonate simultaneously , and the content of mono-alkylbenzene sulfonate was much higher than that of di-alkylbenzene sulfonate .They had maximum absorption at the wavelength of 224 nm , and the absorption coefficients of total alkylbenzene sulfonate and mono-alkylbenzene sulfonate were similar ,higher than that of di-alkylbenzene sulfonate .With total ,mono- and di-alkylbenzene sulfonate as standard substances respectively ,the limits of quantitation were 5 mg/L ,5 mg/L and 10 mg/L ,respectively .The determination result of active constituent was about 3%lower with total alkylbenzene sulfonate as standard substance than that with mono- and di-alkylbenzene sulfonate as standard substances simultaneously ,owing to the weaker absorption coefficient of di-alkylbenzene sulfonate .

    • 摘要: The interfacial dilational rheological properties of 2,5-diethyl-4-nonyl benzene sulfonate(292),2,5-dipropyl-4-nonyl benzene sulfonate(393),and 2,5-dibutyl-4-nonyl benzene sulfonate(494) at air-water and decane-water interfaces were investigated by drop shape analysis.The influences of ageing time,interfacial pressure,dilational frequency,and bulk concentration on their dilational elasticity and viscosity were expounded.The surface adsorbed film was found to be elastic in nature at lower bulk concentration,and its strength determined by the interactions between the molecules in the film.In contrast,a diffusion-exchange process between the surface and the bulk controlled the properties of film at higher concentration.The insertion of oil molecules weakened the interactions among the adsorbed molecules,causing the diffusion-exchange process to dominate the nature of the interfacial film.However,this effect of the oil molecules decreased with increasing short alkyl chain length.The strength of the surface film could be determined before the adsorption equilibrium,while the nature of the interfacial film varied after saturated adsorption because of the re-arrangement of the interfacial surfactant molecules.%利用悬挂滴方法研究了2,5-二乙基-4-壬基苯磺酸钠(292)、2,5-二丙基-4-壬基苯磺酸钠(393)和2,5-二丁基-4-壬基苯磺酸钠(494)在空气-水表面和正癸烷-水界面的扩张流变性质,考察了时间、界面压、工作频率及体相浓度对扩张弹性和粘性的影响.研究发现,在低表面活性剂浓度条件下,表面吸附膜类似弹性膜,其强度由膜内分子的相互作用决定;高浓度下体相与表面间的扩散交换过程控制表面膜的性质.油分子的插入导致界面吸附分子之间相互作用的削弱,扩散交换过程主导界面膜性质;但随着短链烷基长度增加,油分子的影响变小.表面膜的强度在吸附达到平衡前已经决定,而界面膜在吸附饱和后仍然随界面分子重排而变化.
